In many cases when removable media (e.g. External Hard disks, pen drives, SD cards etc.) get corrupted, they only way they can deal with it the next time they are used is by displaying the following message when they are plugged in:
Removable Disk is not formatted, Do you want to format it now?
Often the immediate response to this message (having never seen it before, and especially when you have valuable information on the media), is to select yes, without thinking, hoping that will solve the problem of helping you view the important files you want to access.. only to find that by doing this you have made things even WORSE!. However, help is at hand, as even if you have selected "yes" (which we strongly recommend you NOT doing), we can more than often get your valuable information back. The key is to get your media (pendrive, ext hard drive whatever) to us as soon as possible after this event has occurred, and we can make an assessment of the situation and follow up with an estimate of the cost of recovery of this data. Believe it or not, it is often quite cheap / in-expensive to recover in many cases. So it's usually worth your while to check with us.
